Abstract: 1,154,935. Control of D.C. motors. REGIE NATIONALE DES USINES RENAULT. 27 June, 1966 [3 July, 1965], No. 28787/66. Heading H2J. [Also in Division G3] At least one semi-conductor element, being a diode which conducts in only one direction, a Zener diode, or a transistor, is connected in circuit with a direct-current motor, the semiconductor having such an inherent currentvoltage characteristic that the armature voltage is stabilized after the motor has been started. Speed variations due to changes of load are reduced when compared with those obtaining when the motor is supplied directly or through linear resistors. For motors of the permanent magnet or series type, switch-controlled semiconductors are connected in series or parallel with the armature. In the case of compound motors, the semi-conductors are either in series with the armature and shunt field windings, or in series or parallel with the armature alone.

Patent GB-309053-A (GB)
Title: Improvements in the manufacture of artificial filaments from viscose
IPC: D01F2/06
Filed: 1927-11-01
Abstract: 309,053. Harrison, W. Nov. 1, 1927. Cellulose xanthates, processes for making filaments from.-Strong threads are prepared from viscose by effecting the coagulation in strong or mineral acids of hydrion concentration less than that of 7 per cent sulphuric acid, preferably in the presence of neutral salts, and applying tension with gradually increasing stress to the threads while they are still in a nascent or active plastic state, so that they are extended at least 25 per cent. The duration of the nascent or active plastic state decreases as the hydrion concentration of the coagulating bath increases, and would normally be less than 30 seconds. It is found, however, that that state can be maintained for a longer time if the filaments are passed, immediately or very soon after their formation, into a second bath comprising an aqueous solution of neutral salts and/or organic substances such as sugar, glucose, or alcohol, with or without alkalies. The threads can then be stretched before entering the second bath and/or after leaving it. In one example, viscose of specified quality is spun under specified conditions into a bath comprising specified amounts of sodium and ammonium sulphates and sulphuric acid, and the filaments are passed, as soon as may be, on to a flat, cylindrical, or conical surface moving at a specified rate. and then over means for applying tension gradually. In a modification of the first example, the filaments leaving the bath pass into a solution of sodium sulphate which may contain alcohol, glucose, caustic soda, or ammonia, and stretching is applied at any time after the viscose is sufficiently set. Other examples are given in which the conditions are modified in various ways. The use of zinc viscose also is referred to.

Title: Process and apparatus for manufacturing large bore pipe from thermoplastic synthetic material
IPC: B29C48/28
Filed: 1973-06-21
Abstract: 1438322 Making thermoplastics pipes A G PETZETAKIS 21 June 1973 [21 June 1972] 29552/73 Heading F2P A method of making a large bore pipe from thermoplastic synthetic material, e.g. p.v.c., polyamide or polyolefins such as polyethylene or polypropylene, includes the steps of extruding a hollow element 3 of thermoplastic material, the element 3 having a rectangular outside cross-section and a round inside cross-section, coiling the hollow element 3 at a winding station 1 into windings so as to make the body of a pipe 5 which is rotating about its own axis, introducing a cooling liquid into the hollow element 3 and leading the cooling liquid through at least the first winding, pressing together to effect welding (with the aid of the residual extrusion heat) at side walls of the hollow element 3 and discharging the pipe body 5 thus formed in the axial direction (at the discharge speed V 1 ). As described the hollow element 3 is extruded from an extrusion head 2a and is wound on to a set of winding rollers 6 which are driven synchronously by gearing (not shown). The rollers 6 have a smooth surface at their front ends and a surface with a braking action (e.g. a coating of rubber) at their discharge ends. The speed of rotation of the rollers 6 is arranged so that the pipe is discharged at a speed V 1 . The hollow element 3 is guided on to the rollers 6 by a pressing device consisting of a series of rollers 7 or a pressing finger (not shown) which is arranged to discharge the windings at a speed V 2  which is greater than the discharge speed V 1 . This arrangement presses the windings 13 together and compresses them to ensure a good weld between the windings The residual heat of the extrusion process produces a temperature at the outer surface of the hollow element 3 which is sufficient to ensure welding when the windings are pressed together although additional heat may be supplied by a heater 15. The inner surface fo the hollow element 3 is cooled by a cooling liquid, e.g. water, which is introduced into one or two of the windings by a supply pipe 17 which passes through the extrusion head 2a and which has openings 19 for the cooling liquid distributed over its length. The cooling liquid flows in the direction of the arrows 20, 21. The cooling liquid solidifies the inner surfaces of the hollow element so that it can withstand the axial pressure produced by the pressing device.

Abstract: 1,170,255. Gas turbine combustion chambers; jet propulsion plant. ROLLS-ROYCE Ltd. June 27, 1967 [July 1, 1966], No. 29673/66. Headings F1J and F1L. Combustion apparatus comprises a grid of longerons provided at one end with a nose member in alignment with the adjacent ends of the longerons and shaped to allow substantially laminar flow past it, the nose member having means for providing selectively a sheltered zone for pilot combustion. By the term "longeron" is meant a member extending longitudinally of the grid and whose length is several times greater than its width. The longerons 30 are mounted in a curved duct 19, Fig. 2, communicating at the upstream end with an annular plenum chamber 18 fed with by-pass air from the low-pressure compressor (12) of a gas turbine vectored thrust engine, Fig. 1 (not shown). The duct 19 leads to a swivelling propulsion nozzle 20. Adjacent longerons 30 in the grid are spaced apart to provide slots therebetween, the grid having a compound curvature to follow the bend 35 and the cylindrical portion 33 of the duct wall. A nose member 31 at the leading ends of the longerons 30 has an arcuate chamber 42 which can be supplied with bleed air from the highpressure compressor (13) and an arcuate pipe 44 which can be supplied with liquid fuel. When additional thrust is required from the nozzle 20, valves are opened so that air and fuel flow through facing ports 43, 45 from chamber 42 and pipe 44 respectively into an arcuate recess 46. The fuel/ air mixture leaves the recess as an arcuate curtain providing stabilization for pilot combustion of the mixture in zone 52. An igniter is provided in the latter zone. Main fuel is delivered through pipes 48, 49, 50 to fuel injectors 51 disposed in the slots between adjacent longerons 30. The grid defines with the wall portion 35 a convergent passage 36 so that some of the air entering the passage from the annular chamber 18 flows through the slots between the longerons to mix with fuel from the injectors 51. The slots are shaped as shown in Fig. 4 to produce a more uniform flow. The grid is supported in the duct 19 by a pin 39 engaging a hollow vane 38 and by spaced supports 37, the remainder of the air from passage 36 flowing past the latter supports after cooling the wall 35. A guide vane 55 may be provided to prevent flow separation from the inner wall 47 of the bend. In a modification, the nose member of the grid is formed by a pair of plates hinged at their upstream ends along a transverse axis to provide a stabilizer of adjustable V-shape.
